It sounds like you need to size your squid appropriately. Ensure that
you understand what the directives in the configuration file actually do
before changing them, specifically cache_mem.

If you lower the cache_dir size and then tell squid to reconfigure
itself it will purge objects as necessary until the it is below the
maximum you specified.

You need to find out why your server runs slowly when it has a large
cache - is it memory bound, IO bound or what.
